How about changing that problem sentence in 2.10.1 to:
When a TOKEN is seen where one of those annotated productions could
be used to reduce the symbol, the applicable rule shall be applied to
convert the token identifier type of the TOKEN to:
* The token identifier of the recognized reserved word, for rule 1.
* A token identifier acceptable at that point in the grammar, for
all other rules.
This change would allow
case esac in
(esac) echo match
esac
which is currently invalid and rejected by bash, and when invoked in
POSIX mode, also rejected by yash and zsh. Should that become valid, or
should that remain an error?
(Accidentally sent only to Geoff, re-sending to the list.)
